中间品进口来源地多元化能促进出口产品质量升级吗——基于外部供给冲击视角的研究

Does Diversifying the Sources of Imported Intermediate Goods Promote the Upgrading of Export Product Quality-Research from the Perspective of External Supply Shocks

本文使用2000—2014年中国工业企业数据库与中国海关企业数据库的合并数据,从外部供给冲击视角实证检验了中间品进口来源地多元化对出口产品质量的影响。研究结果表明:中间品进口来源地多元化显著提升了出口产品质量,该结论在进行一系列稳健性检验并缓解内生性问题后依然成立。同时,在面临外部供给冲击程度较高时,企业出于规避断链风险考虑,会构建更加稳定的供应链,此时多元化中间品进口来源地对出口产品质量的提升作用就更为明显。机制分析发现,中间品进口来源地多元化主要通过提高企业风险承担水平和降低生产成本两个渠道提升企业出口产品质量。本文研究结论对于从进口结构调整角度促进出口产品质量升级,推动贸易高质量发展具有重要参考价值。

This paper utilizes the merged data from Chinese Industrial Enterprise Database and China Customs Database from 2000 to 2014 to empirically test the impact of diversifying the sources of imported intermediate goods on export product quality,from the perspective of external supply shocks.The findings indicate that diversifying the sources of imported intermediate goods significantly enhances export product quality,a conclusion supported by a series of robustness tests and the addressing of endogeneity issues.Additionally,firms facing a high degree of external supply shocks tend to establish more stable supply chains to mitigate disruption risks,making diversified import sources of intermediate goods more crucial in improving export product quality.The mechanism analysis reveals that diversification primarily boosts export product quality by enhancing firms'risk management and reducing production costs.These conclusions provide valuable insights for enhancing export product quality and advancing high-quality trade through import structure adjustments.
